COOLING AND WORK TABLE.

Application led March 4.-, 1916.

i the gelatin reproducing process, it is necessary to spread a thinmelted layer of composition over a surface, then cool this layer with aslittle evaporation as possible and keep it cool while it is being usedin the transfer process. lt is difficult, particularly in warm weatherto secure satisfactory results. vIt has been customary to keep an entireworking room cooled to within the required temperature limits. l providea table which is simple in construction and of such character' as. toprovide an easy and successful means for accomplishing the result statedirrespective of the temperature or atmospheric conditions of the room orother place in which the work is being done.

In the drawings accompanying and forming part of the presentspecification I have shown in detail one convenient form of embodimentof the invention which will be set forth fully in the followingdescription.

Referring to said drawings:

Figure 1 is a top plan view of a table involving my invention.

' Fig. 2 is a similar view with the top and end top strips removed.

Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2, looking inthe direction of the arrows but with the top in position.

Fig. l is a transverse section on the line 4-4 of Fig. 2, looking in thedirection of the arrows and having the top in place.

Fig. 5 is a sectional detail on a larger scale of a portion of thetable.

Like characters refer to like parts throughout the several views.

The table comprises in its organization a box-like body such as thatdenoted in a general way by 2, and a hollow top such as that designatedin a general way by 3. The body 2 may be supported in any suitablemanner as by the corner legs 4 and the intermediateand shorter legs 5.

Said body in the present case is open at the top and also at the front.The top Specification of Letters Patent.

opening as shown is closed by the table top 3, and in the presentinstance the front opening is adapted to be closed by the fronts ofseveral trays when the latter are in the in positions thereof as will behereinafter more fully set forth. Said body com-v prises the duplicateends or aprons as 6 adapted to be fastened in some suitable manner tothe upper portions of the legs and the back or re. r apron 7 alsofastened to the legs. l may if desired and as illustrated, fasten to theend apron ('3 linings 8 of some proper insulating` material such asasbestos, felt or ground cork, the linings extending between the twopairs of corner legs 4. The bottoni of the body is denoted by 9 andextends from one end apron (5 to A the other and also abuts against theback apron or rear wall 7. The bottom may as shown be lined as at 10with suitable iusulating material which may for instance be any one ofthose hereinbefore specified or anything else which will answer thedesired purpose when required. Vlithin the body is suitably mounted theframe 9, this frame constituting a suitable support for the bottom orfloor 9. The front of the body comprises the lower strip 11 and upperstripv12 fastened to the front corner legs L I .should note that theintermediate legs 5 abut at their upper ends against the bottom 9. Therear apron 7 and the lower strip 11 are fastened in some convenientmanner to these intermediate legs. The strips 11 and 12 presentpractically thefront of the body 2, the space between them constitutingan opening for the introduction of articles into said box-like body 2,this being the front opening to which l have already alluded. As shownthe end apron 6, the back apron 7 and the lower front strip 11 projectsomewhat below the bottom 9.

1Within the body 2 and forming a part thereof is the frame 13 ofpractically skeleton form. This frame may be connected to the corner orend legs e in any suitable manner. As shown it consists of two duplicateside bars and end and intermediate cross bars connecting the said sidebars, there being any suitable number of crossbars. This frame presentsasuitable support or carrier for the pan (hereinafter described) of thetop 3, it being connected in some convenient manner to the severalcorner legs t.

The top 3 in superficial area corresponds virtually with that of thebody in plan and is preferably hollow, so that it is adapted to receivea suitable cooling medium which may be of any convenient nature, watercooled to the necessary temperature answering satisfactorily in thisregard. As shown the top consists of a pan 14 and a cover 15 therefor,both parts usually being made of metal and being riveted or otherwisesuitably rigidly connected together along the upper marginal portion ofthe pan, the cover or plate 15 which constitutes the top proper of thetable extending outwardly beyond the margin of the pan. The top 3 is ofsuch character as to provide for the circulation of the cooling agenttherein, and the means whereby this particular condition is secured maybe of any desired nature, the partitions 16 arranged in staggered orderin said hollow top meeting my requirement and being as will be inferredone of several ways by which the cooling substance canbe circulated.Fitted into the pan, for instance at f" one end thereof, is an inletpipe as 17, while fitted into the pan at a diagonally opposite point isthe outlet pipe 1S, cold water or the ike being supplied into the pan bythe pipe 17, taking the course of the arrows in Fig. 1 and leaving thepan by way of the discharge or outlet pipe 18, the water circulating inthe pan between the two pipes or ducts thus not only cooling the top 3in an adequate manner but also the space in the body 2 below the pan.

The pan 14 is shown as sustained by the frame 13, the overhangingportion of the plate or cover 15 resting on filling pieces 19 united tothe upper edges of the end aprons or walls 6, back or rear apron 7 andupper front strip 12, the consequence being that when the top 8 is inoperative position, it closes the upper opening in the box-like body 2.Said body is adapted to receive within it means for removably supportingone or more composition coated. elements and for this purpose one ormore trays or shelves may be provided. I have shown several of suchtrays, each being denoted by 20. The end insulating linings 8 may asshown be provided with supporting and guide members as 21 to receive andsupport the respective trays. Vhen said trays are closed as shown forexample in 'F ig. 2, their fronts are superimposed between the strips 11and 12. As a result when the trays are in, the space within the body 2will be closed. Said tray fronts may as shown be provided with pulls as22. It will be perceived that there is considerable space or intervalbetween the uppermost tray 0r shelf 20 and the pan 1st.

in using the table the following procedure may be adopted: Gelatin orother suit able composition is placed generally in a thin layer on asuitable part such as sheet metal. The gelatin-coated pieces are placedon the shelves or trays 2O when the latterare out. The tray or trayswhich are out, are after the positioning of the gelatincarrying parts,pushed in, so that the gelatin or the like on said platescan be cooledand the cooling action l might note, requires but little time. The flatmetal top of the table absorbs the heat from the plate covered with thecomposition when this plate, with the said composition previouslycooled, is placed on said table top, the consequence being that thecomposition is kept cool for as long as may be required in carrying thereproducing process into etl'ect.'

rlhe body 2 may be provided at its corners with the finishing plates 23to cover the joints. l have described in detail a table suitable for mypurposes and the idea in being minute in description is to enable thoseskilled in the art to practise the invention. As will be clear, l do notrestrict myself to any details.

What i claim is:

A cooling and work table having a hollow body open in the top and havingan opening in the front, said body also having a frame therein below theupper edge thereof, a hollow top resting on the trame and comprising acover overlying the upper marginal edge of the body, a series of traysinsertible through the front opening of the body, the trays havingfronts which collectively close the front opening ot thek hollow bodywhen the trays are in, the upper tray being spaced from said hollow topand the latter having means for the entrance, circulation and dischargeof a cooling substance.

In testimony whereof I atlix my signature in presence of two witnesses.
